From 1 January 2026, IMO’s enhanced Data Collection System requires ships to report:

• Fuel consumption per consumer type, main engine, auxiliaries, boilers, others, not just total bunkers.
• New sailing underway condition, from BOSP to EOSP (Begin / End of sea passage)
• Report separate fuel consumption for ‘underway’ and ‘not underway’ condition.

For many fleets, that means one thing: the measurement infrastructure needs to be in place now. At VAF, we’ve spent 85 years developing the sensors and systems that make this straightforward:

• AQ-Rate mass flowmeters: direct kg measurement per consumer type, classification-approved
• ViscoSense®: viscosity sensor
• T-Sense® shaft power meter: verified shaft power for ME efficiency (SFOC), EEXI and CII compliance
• IVY® cloud analytics: real-time CII, EU ETS and FuelEU reporting from a single platform

The 2027 DCS submission reflects what you measure in 2026. Fleets that treat this as an instrumentation challenge, not a paperwork challenge, will be the ones with audit-ready data and stronger CII ratings.

If you’re evaluating your fleet’s readiness for enhanced DCS, we’d be glad to help.
